Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, and in particular to a drying device for spice raw materials. Background Technology

[0002] Spices (such as star anise, cinnamon, and cloves) typically contain high moisture content after harvesting and require drying for storage, transportation, and subsequent processing. Traditional natural sun-drying is highly susceptible to weather conditions, has a long cycle, and is prone to dust and insect contamination, leading to quality degradation. Therefore, hot air drying equipment has emerged for drying spices. While existing hot air drying equipment is highly efficient, it generally suffers from uneven heat distribution. Furthermore, temperature-sensitive spices are prone to aroma volatilization or charring due to localized overheating, affecting product quality. In addition, existing drying devices are in a static drying state after the materials are laid out. During the drying process, spices shrink due to moisture loss, which may cause pores or clumps in the material layer. This causes the hot air flow to 'short-circuit,' preferentially passing through areas of low resistance, resulting in uneven drying and affecting overall quality. Utility Model Content

[0003] The purpose of this invention is to provide a spice raw material drying device that improves heating uniformity, drying efficiency, and quality.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a spice raw material drying device, comprising a drying chamber and a door located on the side of the drying chamber, one side of the door being hinged to the drying chamber and the other side being provided with a locking component between the door and the drying chamber, the drying chamber having an air inlet communicating with the inner wall at the lower center and an exhaust port communicating with the interior at the upper center, the air inlet of the drying chamber being connected to a heating air mechanism, and a vertical main air duct being provided in the middle of the inner wall of the drying chamber, the lower end of the main air duct being connected to the air inlet. The main air duct has several branch air ducts extending laterally toward the side wall of the drying chamber. Each branch air duct has multiple air outlets on its side. The side wall of the drying chamber is provided with several horizontal material trays above the branch air ducts. Each material tray has several ventilation mesh holes at its bottom. The material trays are slidably connected to the drying chamber. The top of the inner wall of the drying chamber is also provided with a material leveling mechanism for turning over and leveling the spice raw materials in the material trays. A controller is provided on the outside of the drying chamber. The controller is electrically connected to the heating air mechanism and the material leveling mechanism.

[0005] By adopting the above technical solution, the material tray is pulled out of the drying chamber by opening the door, and the spice raw materials to be dried are evenly spread on the material tray. Then, the material tray is pushed into the drying chamber, the door is closed, and the locking component is used to position the door on the drying chamber. The controller controls the heating air mechanism to send hot air into the drying chamber through the air inlet. The hot air is introduced into each branch air duct through the main air duct and led out to the bottom of the material tray through the air outlet on the branch air duct. This setting effectively improves the heating uniformity of the spice raw materials on the material tray. During the drying process, the controller controls the material leveling mechanism to turn and spread the spice raw materials on the material tray at regular intervals, which can effectively improve the drying efficiency and drying quality.

[0006] A further feature of this invention is that the heating air mechanism includes a centrifugal fan, an air duct, and a heater. The two ends of the air duct are respectively connected to the air inlet of the drying chamber and the centrifugal fan. The heater is installed on the air duct. Both the centrifugal fan and the heater are electrically connected to the controller.

[0007] By adopting the above technical solutions, we can utilize relatively common equipment, which is cost-effective, readily available, and easy to maintain.

[0008] A further feature of this invention is that the material equalization mechanism includes several horizontal guide rails fixed to the top of the inner wall of the drying chamber and corresponding one-to-one with the material trays. Each horizontal guide rail is provided with a slide seat, and each slide seat is equipped with a vertical telescopic component at its lower end. The lower end of the vertical telescopic component is provided with a material equalization rake. A connecting rod is provided between adjacent slide seats. The connecting rod is perpendicular to the horizontal guide rail. A horizontal telescopic component is provided on the outside of the drying chamber. The housing of the horizontal telescopic component is fixed to the outside of the drying chamber. The telescopic rod of the horizontal telescopic component is parallel to the horizontal guide rail, and the end of the telescopic rod extends into the drying chamber and is fixedly connected to the side of one of the connecting rods. Both the vertical telescopic component and the horizontal telescopic component are electrically connected to the controller.

[0009] By adopting the above technical solution, a single horizontal telescopic component can simultaneously drive multiple equalizing rakes to move along the length of the horizontal guide rail, ensuring that the turning and flattening of the spice raw materials on all material trays are relatively consistent, thereby improving drying efficiency and drying quality.

[0010] A further feature of this invention is that a silicone protective sleeve is fitted onto the teeth of the material equalization rake.

[0011] By adopting the above technical solution, the silicone protective sleeve on the material distribution rake can effectively protect the spice raw materials when turning and flattening them on the material tray, preventing them from breaking due to turning and flattening and affecting the drying quality.

[0012] A further feature of this invention is that: multiple air outlets on each branch duct are distributed on opposite sides of the corresponding branch duct, the branch ducts on both sides of the branch duct are arranged side by side at intervals along their length, and the air outlets extend obliquely downward from one end located on the inner wall of the branch duct to one end located on the outer side of the branch duct.

[0013] By adopting the above technical solution, hot air can be avoided from blowing directly vertically upwards onto the bottom of the material tray, which would cause localized overheating and affect the drying quality.

[0014] A further feature of this invention is that the diameter of the air outlet gradually decreases from one end located on the inner wall of the branch duct to the other end located on the outer side of the branch duct.

[0015] By adopting the above technical solution, the structure of the air outlet has the effect of equalizing the flow of hot air brought out from the diversion duct, reducing the impact of the resistance change of the spice raw materials on the material tray on the air velocity during the drying process, maintaining relatively stable air outlet, and avoiding affecting the drying quality.

[0016] A further feature of this invention is that a dehumidification fan is installed at the dehumidification port of the drying chamber, and the dehumidification fan is electrically connected to the controller.

[0017] By adopting the above technical solution, setting up a dehumidification fan can accelerate the dehumidification speed of the drying chamber.

[0018] A further feature of this invention is that a temperature and humidity sensor is installed inside the drying chamber, and the temperature and humidity sensor is electrically connected to the controller.

[0019] By adopting the above technical solution, temperature and humidity sensors are installed to help staff understand the temperature and humidity conditions inside the drying chamber.

[0020] The locking assembly includes a locking rod passing through the door, one end of which extends to the inside of the door and has a locking portion extending to one side, and the other end of which extends to the outside of the door and has a grip fixed thereto along the length of the locking portion. A telescopic spring is fitted on the portion of the locking rod located on the outside of the door, and the two ends of the telescopic spring abut against the outside of the door and the side of the grip, respectively.

[0021] By adopting the above technical solution, the staff can hold the handle, push the locking lever, further compress the telescopic spring, and then rotate the locking lever to cancel the positioning relationship between the door and the drying chamber, which is very convenient and quick.

[0022] A further feature of this invention is that the drying chamber includes an outer chamber and an inner chamber, with a gap between the outer chamber and the inner chamber, and a heat-insulating material is provided between them to form a heat-insulating layer.

[0023] By adopting the above technical solution, the insulation layer can effectively reduce heat loss inside the drying chamber and reduce energy consumption.

[0024] The beneficial effects of this utility model are: 1. Several branch air ducts extending to the bottom of the material tray are connected to the main air duct. Each branch air duct is equipped with multiple air outlets. This configuration effectively improves the heat uniformity of the spice raw materials on the material tray. During the drying process, a horizontal telescopic component can simultaneously drive multiple equalizing rakes to move along the length of the horizontal guide rail, so that the turning and flattening of the spice raw materials on all material trays is relatively consistent, which can effectively improve drying efficiency and drying quality.

[0025] 2. The insulation layer installed in the drying chamber can effectively reduce heat loss inside the drying chamber and reduce energy consumption. Attached Figure Description

The air outlets 6a slope from one end located on the inner wall of the branch air duct 6 to the other end located on the outer side of the branch air duct 6. Extending diagonally downwards, the diameter of the air outlet 6a gradually decreases from one end located on the inner wall of the branch duct 6 to the other end located on the outer side of the branch duct 6; several horizontal material trays 7 are provided on the side wall of the drying chamber 1 above the branch duct, and several ventilation mesh holes 7a are opened at the bottom of each material tray 7. The material trays 7 are slidably connected to the drying chamber 1. Here, the slid connection is a sliding connection composed of a slide rail structure. The heating air mechanism 4 includes a centrifugal fan 41, an air duct 42 and a heater 43. The two ends of the air duct 42 are respectively connected to the air inlet 1d of the drying chamber 1 and the centrifugal fan 41. The heater 43 is installed on the air duct 42. A dehumidification fan 10 is installed at the dehumidification outlet 1e of the drying chamber 1. A temperature and humidity sensor 11 is installed inside the drying chamber 1.

[0033] Furthermore, such as Figure 1 and Figure 2As shown, the top of the inner wall of the drying chamber 1 is also equipped with a material leveling mechanism 8 for turning over and leveling the spice raw materials in the material tray 7. The material leveling mechanism 8 includes several horizontal guide rails 81 fixed to the top of the inner wall of the drying chamber 1 and corresponding one-to-one with the material tray 7. Each horizontal guide rail 81 is equipped with a slide 82, and each slide 82 is equipped with a vertical telescopic component 83 at its lower end. The vertical telescopic component 83 is an electric push rod. The lower end of the vertical telescopic component 83 is equipped with a material leveling rake 84.

[0035] Working principle: Open the door 2 and pull out the material tray 7. Evenly spread the spices to be dried on the material tray 7 and push it into the drying chamber 1. Close the door 2 and secure it using the locking assembly 3. Set the drying temperature, humidity range, material equalization interval, material equalization time, horizontal telescopic component 86 extension range, and vertical telescopic component 83 extension range via the controller 9. After starting the device, the centrifugal fan 41 heats the air through the heater 43 and then forces it into the main air duct 5 through the air inlet 1d on the drying chamber 1, which is then distributed to the branch air ducts 6. Then, the air is blown out from the air outlet 6a at an angle downwards, penetrating the material layer of the material tray 7, and uniformly heating and drying the spice raw materials. The hot and humid air is discharged from the exhaust port 1e at the top of the drying chamber 1 by the exhaust fan 10. The exhaust fan 10 adjusts the exhaust volume according to the feedback from the temperature and humidity sensor 11. The horizontal telescopic component 86 and the vertical telescopic component 83 in the material equalization mechanism 8 work in a timed and limited manner to drive the material equalization rake 84 to flip and flatten the spice raw materials on the material tray 7. After drying, the equipment is turned off, the chamber door 2 is opened, the material tray 7 is pulled out and the finished product is taken out.
